Specification of Letters Patent.

Patented June 24, 1913.

To all whom it may concern Be it known that we, THOMAS L. GREGSON and JAMES I. FAYETTE, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Wire-Strippers, of which the following is a specification.

Our invention relates to improvements in wire strippers, and has for its object to provideia new and improved apparatus for the stripping of both duplex and single wires. It is illustrated in the accompanying drawings, wherein I Figure 1 is an end elevation. Fig. 2, a section along the line 4-4 of Fig. 1; Fig. 3, a sect-ion along the line. 5-5 of Fig. 1.

Like parts are indicated by like letters throughout the several figures.

The handles A, A are provided with the inwardly extending lugs C upon which the jaws C C are held by means of the rivets C The jaws C C areprovided with the tapering recesses D, from the bottoms. of which project the knives D ,The jaw C is provided with the recess D approximately semi-circular in cross section and tapering, and adapted to register with a corresponding recess D in the jaw C whichrecess has projecting from its bottom the knife D, the edges of the knives D D being arranged at an angle of ap roximately with the two adjacent surfaces of the jaw members. The jaws C C are provided also with a triangular recess D.

It will be evident that while we have shown in our drawings an operative device, still numerous changes might be made in the size, shape and arrangement of parts without departing materially from the spiritof our invention. We wish, therefore, that our drawings be considered as in a sense diagrammatic.

The use and operation of our invention are as follows: The duplex wire to be stripped is seized between the jaws of the implement in such a manner that a plane passing between the two wires may include the cutting knives of the instrument. The handles are compressed and the jaws are drawn along the length of the wire, thus cutting the outer covering of the-duplex. The single wire is then placed in the smaller recess andtthe operation is repeated, the single knife upon oneof the edges acting to split the fiber and insulation whereby it can be conveniently pulled off. Any small particles of insulation or any foreign matter which may remain can be stripped off by drawing the Wire through-the small triangular recesses between thetwo jaws.

In our preferred form we show a knife arranged with its edge at an angle of 45 to the direction of motion of the wire. This is done in order that the cutting may not be done all at one point and adds greatly to the ease with which the wire may be stripped.

We claim a 1. A wire stripper comprising a pair of rectangular recessed blocks and U shaped spring handle having one of said blocks at either end, recesses in each of said blocks registering one with the other and tapering knivesupwardly projecting from the bottom of said recesses.

2. A wire stripper comprising a pair of rectangular recessed blocks and U-shaped handle having one of said blocks at either end, the recesses in each of said blocks being in register one with the other and tapering knives upwardly projecting from the bot tom of said recesses.
